U.S. stock futures fell sharply on Monday morning as Wall Street added to the large losses suffered last week.

Futures for the Dow Jones Industrials tumbled 229 points, or 0.9%, to 25,199

S&P 500 futures docked 13 points, or 0.5%, to 2,743.75, while futures on the NASDAQ Composite faded 43.5 points, or 0.6%, at 6,712.25

The Dow fell 665.75 points on Friday — or 2.5%— notching its biggest one-day sell-off since June 2016. The S&P 500 had its worst one-day performance since Sept. 2016 and the NASDAQ posted its worst session since August 2017.

Equities benefited from strong economic data and solid corporate earnings growth at the start of the year. But increasing inflation concerns have sent interest rates higher recently, rattling Wall Street.
